First split salt into its components Na-Sodium and Cl-Chlorine; take a look at the periodic table and you'll see the atomic number (at the top of the box of an element) that number is how many protons are in the element, so you add the atomic number for sodium-11 to the atomic number for chlorine-17 and you get 28 protons all together in salt, that means that you must also have 28 electrons (the number of electrons must be the same as the number of protons). Now to solve for neutrons take a look at the number at the bottom of the periodic table (known as the mass number or amu or atomic mass units-not shown on all periodic tables so you may have to look it up) for Sodium it's 22.98977 and for Chlorine it's 35.4527 now what that means is the weighted average mass of all the isotopes of the element, what you can do is round that number to 23 and 35, then add those two numbers together making 58 ( the total number of protons + neutrons) then subtract 28 from 58 to give you 30 neutrons (though the number of neutrons varies depending on the isotope of the elements 30 neutrons is the most common isotope of salt). That leaves you with a grand total of 28 protons, 28 electrons, and 30 neutrons.

The number of protons in an atom is different for every element. If you look at the periodic table, then the number labeled "atomic number" is the number of protons.

yes. the atomic weight of an atom is determined by how many protons and neutrons it has. determine the number of neutrons by subtracting the atomic number from the atomic mass

We are not sure if the theorized Higgs boson is real or not. If it is, it would be provide some support to ideas about what mass (and, therefore, gravity, which is associated mass) really is. We're still looking for experimental support that the Higgs boson is real, and now that the Large Hadron Collider is up and running, all (interested) eyes are on CERN and awaiting results.

The Higgs boson has not yet been discovered. It has been predicted by numerous physicists (the best known is probably Peter Higgs, since the particle was named after him, but more people worked on it) and many think that it is required to explain certain features of the Standard Model, which is the model which describes particle interactions at a small scale.

Recently FermiLab has published results which show they may have found the Higgs boson in their collider experiments, but the uncertainties are still too great to be able to claim with confidence that the particle has been found.

If it exists, it will be found by the LHC-experiment at CERN.

Quarks. Up and down quarks, I think. Google quark.

The electrons of an atom are located in the electron cloud.

neutron, uncharged elementary particle of slightly greater mass than the proton. It was discovered by James Chadwick in 1932. The stable isotopes of all elements except hydrogen and helium contain a number of neutrons equal to or greater than the number of protons. The preponderance of neutrons becomes more marked for very heavy nuclei. A nucleus with an excess of neutrons is radioactive; the extra neutrons convert to protons by beta decay (see radioactivity). In a nucleus the neutron can be stable, but a free neutron decays with a half-life of about 17 min (1,013 sec), into a proton, an electron, and an antineutrino. The fact that the neutron possesses a magnetic moment suggests that it has an internal structure of electric charge, although the net charge is zero. The electron-scattering experiments of Robert Hofstadter indicate that the neutron, like the proton, is surrounded by a cloud of pions; protons and neutrons are bound together in nuclei by the exchange of virtual pions. The neutron and the proton are regarded by physicists as two aspects or states of a single entity, the nucleon. The antineutron, the neutron's antiparticle, was discovered in 1956. The neutron, like other particles, also possesses certain wave properties, as explained by the quantum theory. The field of neutron optics is concerned with such topics as the diffraction and polarization of beams of neutrons. The formation of images using the techniques of neutron optics is known as neutrography. See D. J. Hughes, Neutron Story (1959); K. H. Beckurts and K. Wirtz, Neutron Physics (tr. 1964); P. Schofield, The Neutron and Its Applications (1983).

This is a chemical element. You can find the how many electron in a single atom by using a periodic table.

There are several subatomic particles. In general the term refers to the three main parts of an atom - the proton, the neutron, and the electron. But the proton and neutron are made up of even smaller particles called quarks (there are 6 of those!) and then there are all sorts of gluons and mesons... but I think the basic answer is the one that you want. Stick with proton, electron, and neutron.

SOME sub-atomic particles will decay into other particles. For example, a neutron will spontaneously change into a proton, an electron, and a neutrino.

Antimatter was discovered by Paul Dirac in 1928.

no, a molecule is composed of 2 or more atoms.

I'm assuming that by "change" you mean alter the quantity thereof. If you want to actually change a proton into a nuetron and eject a positron, that requires a nuclear reaction.

The protons and neutrons are in the nucleus and serve to define the atom, while the electrons orbit the nucleus and ultimately determine the atom's charge. Electrons can be removed or added with a certain amount of energy. This energy is relatively small compared to the massive amounts required to alter the subatomic particles within the nucleus.

Neutral atoms do. Neutral atoms need the same number of positively charged protons in the nucleus to balance that same number of negatively charged electrons in their orbitals around that atom's nucleus.

Depends on how many electrons it gains. For every electron it gains, the atom becomes more negative. One electron gives it a -1 charge, 2 a -2 charge and so on

jimmy neutron is a character created by Nickelodeon that is a a kid genius and has extremely idiotic friends when ever jimmy has a idea he thinks is brilliant he goes with it and it always back fires hes a know it all and is secretly loves Cindy vortex it is a kids show but it was canceled how did they make them

He was also named after scientist, James Chadwick. Jimmy is short for James and he discovered the Neutron. Jimmy Neutron is also named after Isaac Newton (Jimmy's middle name is Isaac).

any time there are as many electrons and protons and they fill each orbital optimally.

Tachyons are imaginary subatomic particles that always travel faster than light.
